Transcranial Focused Ultrasound Modulates Electrical Behavior of the Neurons: Design and Implementation of a Model [PDF]

Journal of Biomedical Physics and Engineering, 2020
Background: Recently, ultrasonic neuromodulation research has been an important and interesting issue. Ultrasonic neuromodulation is possible by the use of low-intensity transcranial focused ultrasound (tFUS) to stimulate or inhibit the neural structures.

ActionPytential: An open source tool for analyzing and visualizing cardiac action potential data

Heliyon, 2023
The action potential forms the basis of cardiac pacemaking, conduction, and contraction. Action potentials can be recorded from numerous preparation types, including ventricular or atrial trabecules, Purkinje fibers, isolated cardiac myocytes.

A Mathematical Study of Effects of Alzheimer’s Drug Donepezil Hydrochloride on Neuronal Viscoelasticity and Action Potentials

Mathematical and Computational Applications
Alzheimer’s disease (AD) is a degenerative disorder characterized by progressive cognitive decline and memory loss. The few contemporary therapies may ease symptoms and/or slow down AD progression but cannot cure the disease.

Topological Regulation of Synaptic AMPA Receptor Expression by the RNA-Binding Protein CPEB3

Cell Reports, 2016
Synaptic receptors gate the neuronal response to incoming signals, but they are not homogeneously distributed on dendrites. A spatially defined receptor distribution can preferentially amplify certain synaptic inputs, resize receptive fields of neurons ...

The DBI Action, Higher-derivative Supergravity, and Flattening Inflaton Potentials [PDF]

, 2016
In string theory compactifications it is common to find an effective Lagrangian for the scalar fields with a non-canonical kinetic term. We study the effective action of the scalar position moduli of Type II D$p$-branes.

Contralateral inhibition of click- and chirp-evoked human compound action potentials [PDF]

, 2017
Cochlear outer hair cells (OHC) receive direct efferent feedback from the caudal auditory brainstem via the medial olivocochlear (MOC) bundle. This circuit provides the neural substrate for the MOC reflex, which inhibits cochlear amplifier gain and is ...

Taurine depletion during fetal and postnatal development blunts firing responses of neocortical layer II/III pyramidal neurons

Frontiers in Molecular Neuroscience, 2022
Fetal and infant brains are rich in maternally derived taurine. We previously demonstrated that taurine action regulates the cation-chloride cotransporter activity and the differentiation and radial migration of pyramidal neuron progenitors in the ...

Deforming tachyon kinks and tachyon potentials

, 2006
In this paper we investigate deformation of tachyon potentials and tachyon kink solutions. We consider the deformation of a DBI type action with gauge and tachyon fields living on D1-brane and D3-brane world-volume.

Matrix Ernst Potentials and Orthogonal Symmetry for Heterotic String in Three Dimensions

, 1997
A new matrix representation for low-energy limit of heterotic string theory reduced to three dimensions is considered. The pair of matrix Ernst Potentials uniquely connected with the coset matrix is derived.
